F = M A = (13) x (25) = 325 newtons
Galileo Discovered Inertia, he dropped two items from the tower of pisa and realized they fell at the same rate of speed which is approximately 9.29 mps2
It means mps2 .How fast you travel (i.e. your speed) is writen as metres per second (m/s) : e.g. 1 m/s means that in one second you travel 1 metre.However, acceleration is different to speed. It measuring the change in speed per second. Basically it's metres per second divided by seconds.It means the change in acceleration metres per second per second.e.g. If you go from doing 30mps to doing 31mps and it only takes a second for you to do do that, then you've accelerated at 1m/s/s or 1ms2. If it takes you 2 seconds to go from doing 30m/s to 31 m/s then clearly you're acceleration is 0.5 m/s/s (0.5m/s2)
